PATTERNED JEWELERS' STOCK original Filed May 21, 1962 BY F Q 5 l/nd ATTORNEYS United States Patent O 1 Claim. (Cl. 29-183) This invention relates to jewelers stock of the sort that would have some pattern eifect and is a division of my co-pending application, Serial No. 196,128, led May 2l, 1962.

Heretofore, there has been provided certain sorts of jewelers stock which may be of precious metal, such as gold, and which would have a variegated appearance by reason of chunks of metal of one color being dropped into a metal of a different color which was in the fluid or liquid state .but near solidication so as to provide a variegated or marbleized effect. This sort of an effect, however, is one which could not be reproduced because of the haphazard operation of dropping solid chunks into molten metal which could never be exactly repeated because the method of production did not lend itself to exact reproduction, there being no particular control of the dropping of the solid chunks into the molten mass.

One of the objects of this invention is to provide a piece of jewelers stock in which the pattern may be controlled so that it may be reproduced at will.

Another object of the invention is to provide a jewelers stock which may have a large variety of patterns formed therein by predetermination or calculation as to what the nished result should be.

Another object of this invention is to provide a highly decorative piece of stock which may be made up into various articles of jewelry as occasion may require.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claim.

in the accompanying drawings:

FIG. l is a perspective view of Ya number of relatively thin pieces of material secured together in face to face relation with each of the strips of diiferent color and none of the two colors of material being in contact with one another, thus providing a contrasting relation across the edges and ends of the composite assembly;

FIG. 2 is a perspective view illustra-ting a slice taken off the assembly at right angles to the faces of the strips showing lengthwise stripes formed in the plate thus provided;

FIG. 3 shows a plurality of places such as shown in FIG. 2 superimposed one on the other in such a relationship that the stripes of one color do not come in face to face contact with the stripes of another color, thus providing a sort of checkered pattern eiect on the ends of the assembly;

FIG. 4 is a plan view of a slice taken parallel to the end face shown in FIG. 3 after the slice has been rolled in the direction of the arrow shown in FIG. 4; and

FIG. 5 is a view similar to FIG. 4 showing a slice after it has been rolled in the direction of the arrow shown in FIG. 5.

In proceeding with this invention, I have assembled material of contrasting colors in face to face relation so that when viewing the edges of the materials assembled, there will be stripes of different colors, the same also appearing in the ends of the assembly. I then cut at right angles to the faces of the material which has been so assembled a plate therefrom. From a similar assembly ending up with different colors at the ends, I cut ice another plate and then assemble these different plates so that no two colors are in contact with each other, thus providing at the end of the assembly different colors in somewhatof a checkerboard or plaid effect. At this p oint aV slice may be taken parallel to the end face provlding a second plate, and this second plate thus formed may be further treated by rolling which will distort somewhat the checker eiect which is provided, the distortion being different depending upon the different direction of reducing rolling which may occur and the number of passes through the rolls.

With reference to the drawings in FIG. 1, there is a rectangular strip of red gold 10, a rectangular strip of green gold 11 and a rectangular strip of white gold 12 shown in face to face contact along the lines 13 and 14 which repeat in these three colored strips so as to provide a composite block such as shown in FIG. 1. The strips are soldered together to provide the block shown. This block may then be severed at right angles to the faces 15 and along the dot-dash line 16 as shown in FIG. 1 so as to provide a plate, designated as 17, in FIG. 2, having the portions of the strip material .10', 11 and 12' in the repeats as they are shown. In this particular plate the red gold 10 is on one outside edge, While the white gold 12 is on the other outside edge. Another such block as shown in FIG. 1 may be provided in which the green gold 11 may be on the outside edge at one end, and the red gold 10 on the other outside edge as shown in plate 18 in FIG. 3, While the pla-te shown at 19 in FIG. 3 would be plate 17 turned upside down.

These pla-tes 17, 1S and 19 illustrate the red portion 10' .as contacting the green portion 11 in the plate 18, or in other words each one ofthe strips is moved one space or one Athickness of the strip to the left with reference to plate 17 above described. Plate 19 shows the strips 12' as directly below the green strip 11 of plate 18 and thus the strips being moved two spaces to the left with reference to the plate 17 or one space to the lef-t with reference to plate 18. The further plates 20, 21 and 22 are a repeat of the st-rips 17, 18 and 19. T'he plates are secured together' by a thin film of solder, thus slightly increasing the total dimension of Vthe assembly.

In furtherance of the invention, a slice will be taken olf either along the line parallel to the end face and at right angles to the faces of the strips such as 30 or a line parallel thereto which is so as to provide a second plate of the pattern desired. A plate so formed may be rolled down to the desired thickness, and the general pattern elect will remain substantially the same although it will become somewhat distorted depending upon the direction of rolling. Thus, if .rolling is in the direction of the arrow 35 as shown in FIG. 4, each one of the blocks of colored material will become wider inthe direction of Ithe arrow in the iinished rolling, or if the rolling is in the direction of the arrow 36 as shown in FIG. 5, each one of the blocks will become longer slightly than it was previously as shown in the view of FIG. 5. Likewise, if there is a diagonal rolling, there will be a distortion formed .in the form of a rhomboid for each of these diiferent rectangles which are hereabove shown. By the predetermination of the rolling where there is some distortion, tha-t is, knowing the amount that the strip has been reduced, the amount of elongation or distortion may be calculated, and by this method most any pattern may be predetermined and formed in an assembly of diierent colored golds. Such patterns may take the form of letters to make a certain word or other designs which may be found desirable.

By keeping account of the sizes of material used and the reduction by rolling and direction of rolling in any pattern, the pattern may be accurately reproduced by repeat-ing the operation.
